这是我的对话框，我想你可以通过tabbar获得这个想法。我的问题是library resizable_dialog;
import 'package:polymer/polymer.dart';
import 'package:paper_elements/paper_dialog.dart';
@CustomTag('resizeable-dialog')
class ResizeableDialog extends PolymerElement {
ResizeableDialog.created() : super.created();
@observable int selected = 0;
notifyResize() {
$['dialog'] as PaperDialog..notifyResize();
print('"notifyResize" called.');
}
open() {
$['dialog'] as PaperDialog..open();
}
}
在显示之前的某个时刻计算其尺寸。但是，由于我的<paper-dialog>可以有不同的宽度和宽度。高度，每当用户选择一个标签时，我必须调整对话框的大小，以确保当前所选页面的整个内容可见。
由于某些原因，Dart中不存在方法<core-pages>。它在<paper-dialog>.notifyResize()文档中指定了here但我无法调用它，因为它在Dart中不存在。
我该怎么做？如何让对话框重新测量其尺寸？
